"Thanks for your email below and for your continuing feedback.
Another way of filtering alerts is to use the confirmed alerts screens. This screen will filter only those technical analysis alerts that work and move a small amount ino profit, in effect providing additional confirmation of the initial technical analysis alert. For instance, TA-ngo may generate a "Possible support ahead, prior swing low" alert in the technical analysis screen as price approaches a prior swing low. If price holds at the prior swing low and start to move up, the same alert is generated in the confirmed alerts screen. Effectively, all TA-ngo alerts that start moving into "profit" move into the confirmed alerts screen providing a potentially lower risk entry. The downside of course is that the entry may be slightly later.
Once in the confirmed alerts screen, TA-ngo continues to monitor the profitability of the alert. For more information on this, I'd recommend reading the TA-ngo user guide.
When we first set out in developing TA-ngo, we had to make a decision as to the most optimal timescales for intraday trading. We researched all the stocks and assigned a 5 minute or 10 minute timescale for each one depending upon which we felt was most appropriate. Unfortunately, gven the way TA-ngo is structured, we do not have the flexibility to alter these timescales. We can however, add alerts and moving average bands is something we are considering. I personally have not found them to be too useful in my trading and have not found a set of band trading rules that work well. If you do, I should be delighted to include it as an alert.
We are currently testing sending out text alerts and should have that ready in the new year.
The self learning engine can be run for real time intraday or end of day data and we believe will be the most powerful trader's tool out there.
Best of luck with your trading and thanks again for all your kind feedback. If there is anything else, please don't hesitate to let me know.
Best regards
